Comment

Synonymy: Leptognathus alternans FISCHER 1885 was removed from the synonymy of D. incertus by PASSOS et al. (2004). Note that Amaral described garbei and barbouri as new species in two independent papers, published in 1923 and 1926 (i.e., he called them “new” in both the 1923 and 1926 papers).
